Justin Bieber and Ariana Grande might be getting together, but don’t worry Selenators, it’s just business.

On Thursday night, the Biebs posted a tweet about his friend, writing, “[C]ongrats @arianagrande on your number 1 song. #arianabieberduet??”

Grande’s latest release, “Problem,” featuring Iggy Azalea, topped the iTunes charts after its release this week, MTV News reports.

Along with the message, he shared a photo of the two hanging out in the studio, which might have been an under-the-radar Throwback Thursday.

Otherwise, it could signal an imminent duet from one of music’s biggest names and one of its fastest rising stars.

The “Sam & Cat” actress was gracious in her response to Bieber, mysteriously adding, "secrets out now."

Bieber has been on a roll lately, consistently releasing new songs over the past few months, including last week’s “Hard 2 Face Reality.”
